Free Online Grammar Checker — Fix Errors Instantly
Writing mistakes are easy to make and hard to spot. QuickToolkit's free online grammar checker scans your text for the most common English errors — spelling mistakes, missing apostrophes in contractions, wrong word usage, sentence capitalization, and punctuation spacing — and gives you a fully corrected draft in seconds. Unlike Grammarly, there is no account to create and your text is never uploaded to any server. Everything runs locally in your browser, making it the fastest and most private grammar checker available.
How to Use the Grammar Checker
- Paste or type your text into the input box. You can also click one of the sample buttons to test the tool instantly.
- Click "Check Grammar" to scan the text. The tool checks for spelling errors, contraction issues, word confusions, and more.
- Review the Corrected Text tab to see the fixed version of your writing side by side with the original.
- Check the Corrections tab to see a clear list of every type of error that was found and fixed.
- Copy or download the corrected text to use in your document, email, or post.
What This Grammar Checker Fixes
Spelling mistakes
Over 100 common misspellings corrected: recieve → receive, tommorrow → tomorrow, definately → definitely, and more.
Missing apostrophes
Automatically restores contractions: dont → don't, cant → can't, youre → you're, wont → won't.
Word confusions
Catches their/there, your/you're, its/it's, should of/should have, and other common mix-ups.
Sentence capitalization
Ensures every sentence starts with a capital letter and standalone "i" is capitalized to "I".
Punctuation spacing
Removes extra spaces before commas, periods, exclamation marks, and question marks.
Duplicate words
Catches accidental repeated words like "the the", "in in", "to to" and removes the duplicate.
